Abstract
An optically active s-triazine derivative having at least two asymmetric carbon atoms of the general formula: ##STR1## wherein n is 2 to 3; and X and Y are the same or different and are each a member selected from the group consisting of the groups: ##STR2## WHEREIN M IS 1 TO 3; AND R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are the same or different and are each an alkyl having 1 to 12 carbon atoms, a cycloalkyl having 5 to 6 carbon atoms, phenyl or benzyl, and a gas chromatographic method for the resolution and analysis of the mixture of enantiomers having an --NH-- group linked to an asymmetric carbon atom, comprising using said derivative as an optically active stationary phase for the gas chromatography.
